====斯科罗霍德空间 Skorokhod space====

''skorokod space''也写为''Skorohod space''，是所有右连续左极限的函数的数学空间，定义在实线的某个区间上，例如<math>[0,1]</math>或<math>[0，\infty）</math>，取实线或度量空间上的值。<ref name="Whitt2006page78">{{cite book|author=Ward Whitt|title=Stochastic-Process Limits: An Introduction to Stochastic-Process Limits and Their Application to Queues|url=https://books.google.com/books?id=LkQOBwAAQBAJ&pg=PR5|year=2006|publisher=Springer Science & Business Media|isbn=978-0-387-21748-2|pages=78–79}}</ref><ref name="GusakKukush2010page24">{{harvtxt|Gusak|Kukush|Kulik|Mishura|2010}}, p. 24</ref><ref name="Bogachev2007Vol2page53">{{cite book|author=Vladimir I.
